- Figure 1. The ripple-eater design, essentially a filter with a follower, rejects as much as 40 dB in ripple and continues operating even as the supply voltage drops to low levels
- Figure 2. With the transistors shown in Figure 1, the power-supply rejection holds well beyond the audio band
- Figure 3. A higher-power ripple-eater augments the simple design with an additional transistor (Q4) to increase gain
- Figure 4. The more complex design sacrifices high-frequency performance to provide greater output power
